The germination inhibitors in iris seeds are located in the endosperm. They 
are water soluble. They are also ether soluble (1969 info). Excising the embryo 
is another way around the inhibitors. Still, the most practical solution is 
plant the seeds and let nature take its course. Regardless of the method used, 
short of excising the embryo some seeds may take two or more years to 

As a point in passing, sulfuric acid is used on some seeds to weaken or 
remove seed coats. It is also commonly used to remove the lint from cotton seed to 
prepare it for planting.

It is doubtful addition of chlorine to the leeching/soaking process will 
improve germination results.
